%description
Lunzip is a decompressor for lzip files. It is written in C and its
small size makes it well suited for embedded devices or software
installers that need to decompress files but do not need compression
capabilities.

Lunzip replaces every file given in the command line with a decompressed
version of itself. Each decompressed file has the same modification date,
permissions, and, when possible, ownership as the corresponding compressed
file. Lunzip is able to read from some types of non regular files if the
"--stdout" option is specified.

If no file names are specified, lunzip decompresses from standard input to
standard output. In this case, lunzip will decline to read compressed input
from a terminal.

Lunzip will correctly decompress a file which is the concatenation of two
or more compressed files. The result is the concatenation of the corresponding
uncompressed files. Integrity testing of concatenated compressed files is
also supported.

The amount of memory required by lunzip to decompress a file is only a few
tens of KiB larger than the dictionary size used to compress that file.
